What is a business overdraft facility?

A business overdraft is a form of commercial credit where a lender sets aside a certain amount of funds for your business to use as they’re needed. It has similarities with a credit card or a line of business credit, with some of the same advantages and disadvantages. A business overdraft is attached to an existing financial account, such as a savings or transaction account with a bank. Once it’s set up and approved, it allows your business to continue withdrawing money from your account even after the balance has reached zero.

A business overdraft facility can potentially offer a substantial amount of funds. The limit on any given account will be set by the lender while you’re applying for the overdraft facility, but it’s possible for an unsecured business overdraft to offer in the area of $100,000. If you’re willing and able to offer security on the overdraft facility, though, this amount can be much larger – potentially into the millions. These are different from how business loans work, which involve granting you a lump sum and having you repay it over a set period in instalments.

How do I compare a business overdraft facility to another?

When it comes to comparing one overdraft against another, there are a few things to weigh up. For starters, as a business overdraft is a facility attached to an existing account, there’s obviously a convenience factor to setting up the overdraft on the account you’re already using. However, if you’re looking to set up a brand-new account for the overdraft facility, or you’re willing to change account, there are several factors that are worth considering as you compare your options.

  • Secured or unsecured – Does the overdraft require securing, or is an unsecured overdraft an option? Some lenders will only offer a secured overdraft if you’re not an existing customer, for example.
  • Interest rate – The interest rate can make a big difference to what you pay on a business overdraft – especially if you need to use a large amount of credit or you’re not able to clear the debt promptly. Be careful, though: the advertised rate that lenders show on their website might not be the exact interest rate you’re offered on an overdraft, as it’s intended as a reference only. Providing security for your loan will lower your rate.
  • Credit limit – Different lenders may offer different credit limits on an overdraft. The financial situation of your business can influence this and secured credit lines will normally offer much higher credit limits.
  • Fees – Different lenders charge very different fees. Some might have no setup cost, but charge a higher annual fee (which is often calculated daily, despite the name). Others might have a higher application fee but charge less per year. Also, some might not openly advertise some fees, simply saying you can find the cost “on application”.

Pros & cons of an overdraft facility


Simple application process

The application process for an overdraft facility is similar to that of a loan application, but can often be completed more quickly. For many lenders, it’s simply a matter of logging onto their website and applying through your account. Of course, if you don’t have a business account with your lender of choice, you’ll need to open one.


An overdraft facility is a very flexible way to access money. You can draw on your credit at any time, without any additional approval needed. You can also repay the money as funds are available, making an overdraft facility very handy if your cash flow fluctuates.

Can be used for almost anything

There are very few restrictions on what you can use the money from a business overdraft for. While you need to provide a lender with details of exactly what you intend to use loan funds for, there’s no such restriction on an overdraft facility, so it can be used on bills, wages, equipment upgrades, special events or expenses to boost staff morale. You do need to use it for your business and not for personal reasons, though, otherwise you’re breaking the terms of your overdraft agreement.

Can be cancelled at any time

Trying to settle a loan early can be something of an arduous process. An overdraft facility can be shut down at any time – provided you don’t currently have anything owing on the account.


Significant fees for going over the limit

If you spend more than your limit on an overdraft facility, you can potentially be hit with some pretty hefty fees, so it’s a good idea to keep a careful eye on your expenses and your account balance once you’ve dipped into your credit.

Higher interest for long term debt

While you only pay interest on the money currently in use, the interest rate on an overdraft facility is generally quite high. This means that if you find yourself caught out by debt and struggling to repay the overdraft, you’ll be paying more significant interest on that debt.

More impact on credit score

As mentioned, a business overdraft facility is a kind of credit. As such, how you use it has a significant impact on your business’ credit rating. This means you might not want to make your limit on the overdraft too high. It’s also wise not to use more than a third of the credit you have available.

Temptation to overspend

Sometimes having the option of going easily into debt can be an unhelpful temptation. While running out of money can force a business to make necessary hard choices or find alternative sources of funding, having the option to easily borrow money can potentially land you in substantial debt by overspending a little at a time. It can also give you a false sense of security about your financial situation.

Frequently asked questions about overdraft facilities

Should I expect high interest on a business overdraft facility?

The exact interest will vary from lender to lender but, as a general rule, a business overdraft will charge higher interest than an unsecured loan but less than a business credit card. It’s worth shopping around for a good rate of interest, although as the overdraft is linked to an existing account, going with a different lender might involve a lot of work transferring your business finances over.

When is an overdraft facility the best choice for business finance?

A business overdraft is best suited to situations where you have fluctuating reserves of cash and a sporadic need for additional funds. For a large, long-term expense – such as a renovation or equipment upgrade – the lower rate of interest on a loan can make that a better choice. If you’re looking for a business loan instead, Savvy’s a good place to start the hunt. With access to some of Australia’s top lenders, you can compare your options and find the right loan for your business.

Does a business overdraft facility cost anything if I'm not using it?

Yes – because the lender needs to set funds aside to have them available for you, it means that it can cost them money if you have an overdraft facility that you aren’t using. As such, some lenders do have fees for a business overdraft that you don’t use (which might be 1% to 1.5% of your overdraft limit per year). It’s worth investigating this if you’re looking at setting up an overdraft facility on your account. Additionally, you’ll continue to pay interest on your outstanding balance even if you don’t access the account in a given month.

Do business overdraft facilities ever have minimum borrowing amounts?

There are some lenders that have a minimum borrowing amount when activating a business overdraft, which could be anywhere from $1,000 to $250,000. They’re in the minority, though, and often working in specialised areas such as agriculture (which tends to have highly seasonal income).

Is the money from an overdraft facility 100% guaranteed to be available?

No – one downside of a business overdraft is it’s also possible for the lender to cancel the facility on their end. While it doesn’t happen very often, it can leave a business in a difficult situation on the rare occasions that is does – especially if you currently have money owing which now needs to be repaid.

Is it a good idea to get a secured overdraft facility?

A secured business overdraft can have a much higher credit limit than an unsecured one, and the rate of interest can be lower. It can potentially give you access to a large pool of funds at better interest than an unsecured overdraft. However, you need to weigh this up against losing some control of your collateral (you can’t sell or upgrade a property used as security) and the potential impact on your credit rating of having such a large amount of credit in play.
